The main advantages of our approach are two. First, our extraction is accurate because it is only based on the existing structure of the processes. Second, our approach is applicable to processes described in different formats, like pictures and videos, as it does not rely on format-specific techniques like NLP. The main disadvantage of our approach is that it is only applicable to semi-structured resources. We argue that this is not a severe limitation because a large amount of know-how on the Web has some degree of structure. This structure is spontaneously created by Web users as it leads to less ambiguous instructions which are more human understandable. Like the DBpedia project [1]}, our system exploits the existing structure of a particular kind of Web repositories to create a large and generic nucleus of Linked Data.
